Grace: Tracking Water From Space shows how apair of satellites effectively "weigh" Earth's shifting water resources month by month, and what this reveals about the impact of climate change on the planet's vast tracts of freshwater, saltwater, and ice.

This feature story is an illustration of the process of science because it shows scientists collecting data that can be used as evidence to evaluate hypotheses about the impact of climate change on Earth's water. (Read more about The Scientific Process.)

This Classroom Discussion Activity can be used to connect your students to the process of science, highlight overarching scientific themes, and enhance comprehension of the story.
